"Through the Smart Vault, we bring a very different, much more convenient, state of art branch experience to the customers," ICICI Bank MD and CEO Chanda Kochhar said after its launch here.

The 'Smart Vault' is an example of 'Make In India' programme as it has been designed and manufactured by Indian partners, she said.

"The vault uses robotic technology to access the lockers from the safe vault and enables customers to access their lockers at any time of their preference," the statement issued by ICICI Bank, country's largest private sector lender, said.

Asked about charges of the digital locker, Kochhar said: "The lockers are of two-three different sizes and charges would depend on that.

Also, the locker charges in a city would vary depending on the real estate cost." Launched in Delhi, Kochhar said the bank would replicate this digital locker facility to a much larger scale in the days to come.
